Hello! To find this answer, we should divide 2/3 by 5. 2/3 * 1/5 is 2/15. That means there are 2/15 cup of strawberries per 1/6 liter. Now, we should multiply it by 6. 2/15 * 6/1 = 12/15 or 4/5 when simplified. The unit rate is 4/5 cup of strawberries per liter.
The problem says that Angela uses 2/3 cup strawberries to make 5/6 liter of smoothies. Then, to find the unit rate in cups of strawberrry per liter, that is cup/liter we need to divide both fractions:
Then, the unit rate in cups of strawberry per liter is That is, Angela uses 4/5 cups of strawberry to do 1 liter of smoothie.
One half of a number represents the phrase "1/2a" (in this case the variable/number is 'a'". Then because it says "nineteen less than", that means you subtract 19 from one half of the variable.
